General Description

The IC is a very low power consump- Package

tion single chip FSK/ASK Superhet-

erodyne Receiver (SHR) for the

frequency band 310 to 350 MHz that is

pin compatible with the ASK Receiver

TDA5201. The IC offers a high level of

integration and needs only a few exter-

nal components. The device contains

a low noise amplifier (LNA), a double

balanced mixer, a fully integrated

VCO, a PLL synthesiser, a crystal

oscillator, a limiter with RSSI genera-

tor, a PLL FSK demodulator, a data fil-

ter, a data comparator (slicer) and a

peak detector. Additionally there is a

power down feature to save battery

life.

Features
